"Happy Valentine’s Day, @michelleobama! Almost 28 years with you, but it always feels new," Obama tweeted.

Michelle Obama followed up with an affectionate tweet of her own.

She posted a photo of their feet in the sand captioned with: "Happy Valentine's Day to the love of my life and favorite island mate, @BarackObama. #valentines."

The Obamas vacationed in the British Virgin Islands with billionaire Richard Branson this month. Barack Obama was photographed on the water, enjoying retirement and trying out kitesurfing with Branson.
